SEAIVI FOR BALL-COVERS, 800.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed April 24, 1906. Serial No. 313,372.

To all whom it may concern:

Be it,known that I, DAVID M. MONTGOM- ERY, a citizen of the United States, and a resident of Fleetwood, in the county of Berks, State of Pennsylvania, have invented certain new and, useful Improvements in Seams for Ball-Covers, &c., of which the following is a specification,

My invention relates to an improved seam adapted particularly for use in uniting the cover sections of base balls.

The main objects are first, to provide a ball having uniting stitches in connection with reinforcing longitudinal stitches running parallel with the abutted edges of the cover sections and engaged by the cross-wise uniting stitches so as to avoid tearing-out of the latter; and second, to provide exposed stitches upon the surface of the ball so as to enable a firmer grip of the same Without incurring the liability of breaking the seam by exposing the unitin stitches as heretofore.

The invention is fully described in connece tion with the accompanying drawings and the novel features are specifically pointed out in the claims.

Figure 1 is an exterior view of a ball, the cover-sections of which are united by my improved seam. Fig. 2 is a separate view of one of-the cover-sections showing the longitudinal reinforcing stitches running parallel with the edge thereof. Fig. 3 is an enlarged cross-sectional view showing the seam. Fig. 4 is a similar view to Fig. 3 showing a modification.

My invention relates primarily to improvements in the game-ball shown in Patent No. 289,297, issued November 27,

1883, to W. B. Melot, which patent provides for a cover seam having uniting stitches below the exterior surface. ent invention is obviously applicable to other uses, it is here shown and described as applied to a game ball in which each of the several features may be advantageously used.

A and B represent the usual similar cover sections of a base-ball formed of leather or suitable fabric. In covering the ball the edges of these sections are closely abutted, as shown in the drawing, by means of concealed uniting stitches 2 in the manner described in the Melot patent above referred to. In my improved seam construction however these imiting stitches are practically secured against pulling-out from the engaged fabric,

Though the pres-- as indicated in Fig. 3, thus enabling the use i of a thinner cover material without undue weakness at the uniting edges; or such reinforcing strips 4 may be omitted, as indicated in Fig. 4. A further object isattained by employing the reinforcing stitches 3 in the manner shown, in covering a ball. In using concealed uniting stitches, as in Melot, While the stitches are thus effectually protected from the wear and tear incident to exposure, an objectionable feature has been the unusual smoothness of surface resulting from locating the stitching below the surface. In my improved scam, the reinforcing stitching 3 being exposed exteriorly as shown, this objectionable smoothness of surface is avoided and a more secure gripping of the ball provided for,'while at the same time the wear andtear to which this stitching is subjected.

has practically no effect upon the strength of the seam.

As previously stated my invention may be otherwise ap lied than above specifically described and s own.

What I claim is 1. A ball having a sectional cover provided with lines of longitudinal stitching adjacent to the abutted edges, said edges being united by cross-stitching below the exterior surface and engaging said longitudinal stitching.

2. A ball having a sectional cover provided with lines of longitudinal stitching adjacent to the abutted edges, said edges being united by cross-stitching engaging said longitudinal stitching.

3. A ball having a sectional cover the abutted edges of which are provided with lines of exposed longitudinal stitching and united by concealed cross-stitching engaging said longitudinal stitching.

4. A ball having a sectional cover the edge portions of which have thickening strips secured thereto by lines of longitudinal stitchstitches, and uniting stitches engagingv both lines of reinforcing stitches.

8. A seam composed of abutting fabric edges each having a reinforcing strip on one face thereof and a parallel line of reinforcing Y stitches, and uniting stitches below one surface of the fabric and engaging both lines of reinforcing stitches.

In testimony whereof, I afiix my signature in the presence of two witnesses.

DAVID M. MONTGOMERY.
